Is 86F too hot for my plants. I have really good ventilation with a 6" vortex sucking the air out of the tent through the hood too cool the 2x600w hps bulbs. There is a also a 4" can fan sucking the air out of the tents, and 2 oscillating fans. 83-86 is the best I can keep it with both lights on, with one it can stay 73. Any thoughts I dont want to stress the plants
